Hi, I've been a great fan of thie plugin, as I find FF to be a great source of well formatted metadata.
However, I've had a few problems. Namely, that some authors that were previously listed on FF are gone (and the ff links in Calibre go dead).

After a while, I finally figured out what was going on: some authors were being moved to ff adults only. It's the same people, but they decided to separate things (which I can understand).

My only problem now is that your plugin only scrapes the main FF site. I figure that if you already have the book in Calibre, you already know what the book is about

Please help me out here, this plugin used to work great and now I can't get it working. I don't know what I'm doing wrong.

Very definitely not getting matches, even for previously matched books, but it could be a local internet problem. Pacific isles can be that way. Latest calibre version and latest plugin version (per the updater)
